Keep the card reader connected to a mobile device.

Keeping the card reader connected to a mobile device shortens the transaction time, so we recommend it for busy, crowded situations.

However, this will have negative effects on its battery life and may require daily charging. If you feel that you are charging too often despite a low number of transactions, we recommend disabling this feature.

1. Sign in to the application as an administrator.
2. Open the main menu by tapping the icon (≡) and go to Settings->Devices->Card reader. 
3. In the right window, move the slider Do not disconnect the card reader after a transaction to the right to activate this option, or to the left to deactivate it.
